Possible Causes

How to Fix / Troubleshooting
Safety first: Turn off power at the breaker. Do not run a pump with loud grinding noises; it can seize and trip breakers.
- Confirm noise source:
- Listen closely to determine if noise is from the motor (rear) rather than the wet end (front housing).
- Check for leaks:
- Inspect the mechanical seal area between pump housing and motor for water leaks that may have entered the motor.
- Short-term mitigation:
- There is no reliable long-term DIY fix for failed bearings; lubrication ports are not provided on modern Jandy motors.
- Permanent repair:
- Replace the motor with a compatible Jandy replacement motor, or replace the entire pump assembly.
- When replacing the motor, always install a new Jandy mechanical seal kit to prevent future leaks.
